Abstract
A kind of exhaust structure for earphone ante-chamber, the earphone ante-chamber is interior to be equipped with exhausting-gas hole, and the exhausting-gas hole is connected with conduit, and the air-flow in ante-chamber is exported ante-chamber by the conduit.In the utility model, air-flow in earphone can be delivered to L-type conduit by the exhausting-gas hole of ante-chamber, L-type conduit can play air-flow certain abirritation, air-flow is delivered to by conduit in the cavity unrelated with loudspeaker back cavity, air-flow disseminates away in the fit-up gap eventually through components such as auricular concha and auricular concha cosmetic sheet, auricular concha stents, thus eliminating the need extruding of the air-flow to horn diaphragm, so as to lift acoustics and noise reduction.
Description
Technical field
Earphone field is the utility model is related to, in particular for the exhaust structure of earphone ante-chamber.
Background technology
At present, with the development of society, people's living standard gradually steps up, requirement of the people to earphone is also increasingly
Height, noise cancelling headphone have become a kind of trend of earphone industry, and the industry of utilization and field are all more and more, acoustics and noise reduction effect
The quality of fruit directly influences the sales volume of noise cancelling headphone.
Utility model content
The utility model is to solve the bad technology for causing earphone noise reduction bad of earphone exhaust effect in the prior art
Problem, there is provided a kind of exhaust structure for earphone ante-chamber, the earphone ante-chamber is interior to be equipped with exhausting-gas hole, and the exhausting-gas hole is connected with
Air-flow in ante-chamber is exported ante-chamber by conduit, the conduit.
Further, the conduit is arranged in the back cavity of earphone, and the tube at one end is connected with exhausting-gas hole, and the other end passes through
Cavity outer wall is outside back cavity afterwards.
Further, the conduit and exhausting-gas hole are sealed connection.
Further, the conduit is L-type conduit.
A kind of earphone, the earphone include the exhaust structure as claimed in claim 1 for being used for earphone ante-chamber.
The utility model embodiment has the beneficial effect that：
In the utility model, the air-flow in earphone can be delivered to L-type conduit, L-type conduit meeting by the exhausting-gas hole of ante-chamber
Certain abirritation is played to air-flow, air-flow is delivered to by conduit in the cavity unrelated with loudspeaker back cavity, and air-flow is final
Disseminated away in fit-up gap by components such as auricular concha and auricular concha cosmetic sheet, auricular concha stents, thus eliminating the need air-flow to loudspeaker
The extruding of diaphragm, so as to lift acoustics and noise reduction.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of embodiment of the utility model.
In figure：1 it is auricular concha, 2 be exhausting-gas hole, 3 is L-type conduit.
Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the part of the embodiment of the utility model, rather than all
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creative work premise
Lower all other embodiments obtained, shall fall within the protection scope of the present invention.
If it is to be appreciated that related in the utility model embodiment directionality instruction (such as upper and lower, left and right, it is preceding,
Afterwards ...), then directionality instruction be only used for explain it is opposite between each component under a certain particular pose (as shown in drawings)
Position relationship, motion conditions etc., if the particular pose changes, directionality instruction also correspondingly changes correspondingly.
If, should " first ", " the in addition, relate to the description of " first ", " second " etc. in the utility model embodiment
Two " etc. description is only used for description purpose, and it is not intended that instruction or implying its relative importance or implicit indicating meaning
The quantity of the technical characteristic shown.Thus, " first " is defined, the feature of " second " can express or implicitly include at least one
A this feature.In addition, the technical solution between each embodiment can be combined with each other, but must be with ordinary skill
Personnel can be implemented as basis, and this technical side is will be understood that when the combination appearance of technical solution is conflicting or can not realize
The combination of case is not present, also not within the protection domain of the requires of the utility model.
The utility model is further elaborated below in conjunction with the accompanying drawings.
Illustrate herein, the cavity in Fig. 1 on auricular concha 1 is the back cavity of earphone.
A kind of exhaust structure for earphone ante-chamber, the earphone ante-chamber is interior to be equipped with exhausting-gas hole 2, and the exhausting-gas hole 2 connects
There is conduit, conduit is L-type conduit 3, the air-flow of ante-chamber is lenitively exported in the cavity unrelated with ante-chamber.
Conduit is arranged in the back cavity of earphone, and tube at one end is connected with exhausting-gas hole, after the other end is exposed to through rear cavity outer wall
Outside chamber；With exhausting-gas hole to be tightly connected, guarantee air-flow can only flow out conduit from conduit, and cannot be from exhausting-gas hole and conduit
Flow out, effectively prevented because the gap between exhausting-gas hole and conduit causes exhaust effect bad in gap.
Wherein, it is particularly important that position of exhausting-gas hole is in ante-chamber, exhaust position determine exhaust effect, and exhaust effect is not
Good, the horn diaphragm of earphone can equally be subject to different degrees of extruding, and certain harmful effect can be equally caused to acoustics.
The position of exhausting-gas hole is apart from the position of loudspeaker central point 27mm.
The specific operation principle of the utility model is：When head-type noise cancelling headphone is correctly applied on head by people, ear muff
It is subject to the extruding of head on both sides can produce air pressure, if without this exhaust structure, the air pressure of generation can produce horn diaphragm
Raw extruding, horn diaphragm are squeezed, and pronunciation will be abnormal, we will hear abnormal sound, such as poop, this exhaust mode
It is based on solving the problems, such as this and designing, air-flow can be delivered to L-type conduit by the exhausting-gas hole of ante-chamber, and L-type conduit can be to air-flow
Certain abirritation is played, air-flow is delivered to by conduit in the cavity unrelated with loudspeaker back cavity, and air-flow is eventually through ear
Disseminated away in the fit-up gap of the components such as shell and auricular concha cosmetic sheet, auricular concha stent, thus eliminating the need air-flow to horn diaphragm
Extruding, so as to lift acoustics and noise reduction.
In the description of this specification, reference term " embodiment ", " some embodiments ", " an implementation
The description of example ", " some embodiments ", " example ", " specific example " or " some examples " etc. means to combine the embodiment or example
Particular features, structures, materials, or characteristics described are contained at least one embodiment or example of the utility model.At this
In specification, schematic expression of the above terms may not refer to the same embodiment or example.Moreover, description is specific
